In Wolkaan two seemingly unrelated films intersect - a fantastical rendering of the city of Tehran under a volcanic eruption that abruptly shifts to a fictional episode in the American Midwest. Each segment, as an incomplete cinematic event, hints at the other; and lingers in a semiotic limbo--awaiting encounter with the other--anticipating some kind of transformation. The film attempts to place the viewer in a zone of collision in order to activate an inaccessible shared memory.
